The IRA Quartermaster General (QMG) runs a department which is responsible for obtaining, concealing and maintaining the store of weaponry of the Irish Republican Army. In the Provisional IRA, the QMG department is large and important department. It works closely with the IRA Engineering Department, which develops weapons.
A number of people have held the post of QMG. In 1997, the then QMG, Michael McKevitt broke away from the Provisional IRA to form the Real IRA, taking PIRA weaponry to his breakaway organization.
